'R DoTYV y 2,377,766 n RECORD PUNGHING MACHINE A1"ToRNEY Patented June 5, 1945 UNITED STATES PATENT oFFlcE RECORD PUNCHING MACHINE Charles R. Doty, Yonkers, N. Y., assignor to International Business Machines Corporation, New York, N. Y., a corporation of NewYork Application April 12, 1944, Serial No. `530,662 l22 Claims. (Cl. 164-115) so that when the punched tape is utilized to conl trol a tape controlled printing machine the interpolated designations punched at predetermined positions of the tape will cause thev printing of corresponding designations or spacing of the tape to render the meaning of the printed tape more l intelligible.

As an explanation for the above, it is well known that the punching of a tape in the Baudot 'code maybe derived from data punched on a record card according to another diiierent or statistical code. Such record cards may have previously been utilized to control record controlled accounting machines; sorting machines and the like and accordingly such cards are made up with a plurality of card columns, one or more making up a card iield. Such card fields are usually adjacent and when utilized in a tabulating system they do not usually include'or require the representations of the extra characters, or

spaces to render the data intelligible. One exan ample would be two card elds punched to represent 12853810987, all run together which isdntended to mean $128,538,109.87 and the latter indicates the manner in which the datai should that it can be understood by the reader. In the present machine the necessary significant characters, punctuation, spaces, etc. are interpolated as tape punching occurs.

A'feature of the invention is the provision of 4,

means responsive to sensing of predetermined positions of the record card to cause, by interpolation, an extra punching operation of the tape to punch representations of the desired characters, space, etc.,necessary at such column posi- 45 tions.

Another feature of the invention is to providestorage of such extra-character representations, space, etc., in a master or pattern card, the card column positions of which are concurrently sensed with the record card. 4 v Another feature of the invention is to provide for the sensing of the perforation of the master or pattern card at predetermined .column posiexists to interpolate punched data by causing the initiation ofthe operation of the tape punching machine to punch in the Baudot code such extra charatcer representations, as space, etc.

Another feature of the invention provides for suppression of ltape punching under control of a .card column of a record card when a perforation is concurrently sensed on the master or pattern card until the extra punching cycle of the tape punching machine is performed to punch the extra designation called for by the pattern card.

Another feature of the invention provides for the suppression of column spacing of the pattern.. and record cards which would normally follow each tape punching cycle of the tape punching machine but enable the normal tape spacing functionyof the tape punching machine for spacing the extra designations punched on the tape.

Another feature of the invention relates to the provision of means for punching the tape at a succeeding column position under control. of the sensed data on the record which punching operation was suspended during the interpolated tape punching operation. Concurrent with this operation, additional means comes into operation to prevent the master or pattern card from being eiective to repeat its con'trol during the cycle of operation that the tape punching machine is operated to punch said sensed data on .the

record.

Another feature of the invention relates to a plurality of control means which select for operation the desired tape punch control magnets Abe printed under control of the punched tape so of the tape punching machine topunch the extra coded designations and the provision of means to selectively associate such control` means with the master or pattern card sensing means. `This selective arrangement enables interpolation of desired data at predetermined positions of the tape.

Other objects .of the invention will be pointed out in the following descriptionand claims and illustrated in the accompanying drawings, which disclose. by way of example. the principle of the invention and the best mode, which has been contemplated, of applyingthat principle.

Before describing in detail the construction and' operation of the present improvements, it should be observed that for the purpose of illustration the present improvement-is shown in connection with a record controlled tape perforating apparatus of the form shown and described in full.

detail in the patent to C. R. Doty, No. 2,340,800. granted February 1, 1944. 'Ihe individual record sensing and tape perforating units shown in detail in this patent are diagrammatically shown 5-unit telegraphic or Baudot, code and accordingly control selectively the energization of the in Fig. 1 wherein it will be seen that they are interconnected by a cable connection CC. To understand the operation of such apparatus a general outline of the functional operations thereof will be set forth brieny.

Individual record cards C (Fig. 2) having co1- umns of either alphabetical or numerical data or both recorded thereon in the Hollerith code are presented to a sensing station by means of a reciprocable card carriage comprising a pusher I3 (Fig. 7). The record card C is fed column by column to the group of individual sensing brushes I2, one sensing brush I2 being provided for each index point`position. The sensing brushes I2 (Fig. 11) are electrically connected to individual translating relays of the group RR, RX, RO, RI-R9, which relays are energized selectively in accordance with the sensed data designations on the record cards. A plurality of control relays o RN, RII, RI2, RIS, RM are connected t0 Certain ones of the translating relays so as to be energized selectively in accordance with'the data sensed onthe cards.

'I'he aforementioned patent discloses in complete detail the translating controlled by the translating relays which, through their associated contacts, are effective to translate tape punch control magnets 290 in diierent code combinations, thereby causing the code designating perforations representing the data sensed on the record cards to' be punched in the tape 200.

The card sensing mechanism will only be described in suiiicient detail for a full comprehension ofthe present invention, since details of the sensing unit are disclosed in the patent to Doty, No. 2,340,800. Furthermore, in view of the fact that the mechanical arrangement of the card feeding and ejecting mechanism is substantially the same as that embodied in the machine known as the International Duplicating Key Punch and Alphabetical Veriiier," such as shown, for example, in U. S. Patent No. 1,914,263, dated June 13, 1933, and U. S. Patent No. 2,107,161, dated February 1, 1938, a condensed description is deemed to be sufcient. Referring to Fig. l, the record cards C to be sensed or analyzed are placed in the magazine II) from which they are advanced singly by a picker I I toward the left, to present the first column of perforations to a card sensing position above The operation of the card feeding mechanism for feeding a card from the magazine I0 and placing it upon thecard carriage to the initial sensing position is fully explained in Patent No. 1,772,186, granted to F. L. Lee et al. for Duplicating punching machine.

The escapement mechanism of the record sensing unit is of the same general nature as that disclosed in the Schaaff Patent No. 1,426,223 modiiied for electrical control as in the Doty Patent No. 2,340,800 and a brief description thereof will now be given.

When the card is in a position above the sensing brushes I2, .the column by column advance of the card carriage is controlled by an escapement mechanism which, in turn, is responsive to the energization of the escape magnet 40 (Fig. 7). Upon energization of magnet 40 its armature 4I will be rocked about a pivot in a clockwise direction and through a screw 42 secured to an arm secured to rod 43 will rock the rod 43 counterclockwlse against the tension of a spring 44. The rod 43 is rocked as an incident to each spacing operation and has secured to one end thereof oppositely extending-arms 45. 46 (see also Fig. 8) of which arm 46 is provided with a laterally ex.. tending pin for engagement with an enlarged opening in a stepping dog 4l which is loosely pivoted on rod 43. Opposite arm 45 is provided a pin extending into a slot formed in the locking dog 4l. When rod 43 is rocked, arm ,46 will, through its pin and slot connection with dog 41, lift the latter out of one of the notches of the escapement rack I5 movable with the card carriage and at the same time arm 45 will depress locking dog 4l into a notch between the ratchet teeth. At this time, spring 49 advances the loosely pivoted dog 41 a short distance just suillcient to permit this dog to move over the top of the next tooth. When the locking d og 48 is again raised, stepping dog 41, due to the-movement of the rack I5 and the 'card carriage, will ride down along the next tooth until it strikes the bottomV thereof and designations sensed in the statistical code to the 1s. the Spring dven we carriage is thereby arrested. It is sufficient to know thereof that for each energization of the escape magnet 40 the escapement rack I5, and therefore the card carriage, is moved the distance of one card column through the action of the pusher |3 and the forward guide I4 on the statistical card. Also in Fig. 8 are shown i the floating cam contacts |49 which are well known in the type of machine now being described. One blade of contacts |49 is'shifted by an arm |50 which is loosely pivoted on the rod 43 and which has a depending extension resting upon the upper edge of the stepping dog 41 so that during escapement from one column to another the incidental raising of the stepping dog 41 and the elevation of arm |50 will cause the opening of the contacts |49 during the period that the dog 41 is raised. When the card carl riage has come to rest after having escaped through the distance of s. card column, contacts |49 willcome to normal position in which they are closed.

Incorporated in the record sensing unit shown in Fig. 1 is an additional sensing device adapted to sense the perforations on the master card M as it will be `called hereinafter (Fig. 3). The" record sensing unit shown in the aforementioned Doty Patent No. 2,340,800 is intendedl to have such supplemental master card sensing device and since the details thereof are not Ydisclosed in this patent, a description will be given of this arrangement.

The master card sensing device is shown in Fig. and is well known as part of the International Duplicating Key Punch. This master card sensing device is fully shown and described in the U. S. patent to Lee and Daly, No. 1,976,618, granted October 9. 1934 to which reference may be had for further details of construction.

For a general understanding thereof it will be observed that the escapement rack |5 is provided with extensions or arms 31 and 41 (Fig. l0), between which the master card M is positioned in columnar alignment with the statistical card C. This comprises,l therefore, a card carriage for the master card which is adapted to be moved back and forth with the escapement rack I5.

Positioned about the master card M is a contact roller 50 which is insulated from the frame of the machine and supported by a door 5| pivoted at 52. Directly below the roller 50 are brushes 53 carried by a bar 54 which is normally in the position shown in Fig. 10, holding the brushes down out of engagement with the master card M. The magnet 55, upon energization, will attract its amature 55, actuating linkage 51 to cause movement of the brushes 53 into engagement with the master card M. f

tions in which they are aligned, circuits will be closed through such perforations to eifect certain functions in the tape sensing unit, as will described hereinafter.

The tape performing ma Fig. 9 represents the construction of the tape perforating unit to disclose the elements necessary to understand the present improvement. To secure full details of the construction and operation of this unit, recourse may be had to the aforementioned patent to C. R. Doty. No. 2,340,- 800. In general, the perforating portion includes individual punch elements 2|0, one for each unit of the Baudot code, which punch elements are reciprocable in a die block 2|| to perforate the tape 200 according to the punch elements selected for operation. 2|1 represents interposers individual to punch element 2|0, each of whichhas a strap 2|8 which is operated by an eccentric cam 2|9 carried by the drive shaft 220 of thetape perforating unit. Normally, during the rotation of the eccentric cam 2I9 each interposer is moved downwardly and upwardly by the supporting eci centric about the pivotal connection `2|i formed by the end of the interposer engaging the recess of the related punch element. f

,'For each interposer 2|1 there is provided an individuallatch arm 222. Whenever it is desired to select a punch element 2|0 for operation the related latch arm 22 is rocked in a clockwise direction so that its latch fingers 226 engage and latch the free end of the related interposer 2|1. Thus, upon latching of an interposer 2|1 and rotation of the eccentric 2|9 the said interposer is positioned by the'eccentric about the pivotal connection formed by the latch arm 222 and the latched end of the interposer to force the related punch element 2|0 downwardly, thereby causing the tape 200 interposed between the lower ends of the punch elements 2|0 and the die block 2|| to be perforated.

The control means for selectively positioning the latch arms 222 and thereby select the punch elements 2|0 for operation consists of the punch selecting magnets 290. 'I'he armature 29| of each magnet 290 hasconnected thereto an arm 292 and the latter has a call wire connection 293 between the related arm 292 and the latch arm 222. Hence, the'energization of each magnet 290 positions the related latch arm 222 so as to eifect the It is well known that a series of brushes 53 is l provided to analyze all the index point positions ofthe master card M but in Fig. 11 only the sensing'brushes 53 for analyzing the 1, 8 and 9 index point positions of the master card are shown because only such positions are utilized herein to effect extra coded pnchings in the tape sensing unit. It should be observed that vprior to the beginning ofthe concurrent analysis of a mastercardlM and a statistical card C the magnet 55 is i energized to elevate the sensing brushes 53 and 'by circuit connections described in the Doty patent the magnet 92 (Fig. '1) is also energized to elevate the brushes l2 for sensing the statistical card C. Thereafter, there is a concurrent stepby-step escapement of the master card M and statistical card C and whenever the brushes 5l encounter perforations at the index point posioperation of the related punch element 2|0.

Other elements shown in Fig. 9 are involved in the punching operation but they are not described herein since full details of their construction and operation may be had by reference to the aforementioned patent to Doty, No. 2,340,800.

By means more fully described in the aforementioned patent, substantially centrally located feed perforations 202 (Fig. 4) are formed as the tape is perforated. The paper tape 200 is drawn from a supply roll (not shown) tothe punching station by a feed roll 240 secured to a drive shaft 24|. Said feed roll 240 is formed at its periphery with teeth 243 which cooperate with the feed perforations 202 of the tape 200. The step-by-step rotation of the feed roller 240 feeds the tape 200 so as to present successive columns of the unperforatedtape 200 to the punch elements 2|5.

The operation of the punching mechanism of of the tape feeding mechanism performed in the necessary sequence, is effected upon energi'zation of the tape clutch control magnet 250,(shown in the wiring diagram of Fig. i1; Infthe bey patent, complete details are shown .of the manner in winch such magnet initiates the operation of the tape perforating unit. For understanding I the present improvement it is suiiicient to know that this initiates the operation of the-drive shaft 220, the shaft 24| for feeding the tape and other operating elements of the tape perforating unit to eiect the tape punching and feeding operations.

operation The general operation of the machine will now be given in connection with the circuit diagram of Fig. ll and a more detailed description will be given oi the present improvements exemplified by the example of Fig. 5 when that point ofthe speciiicationisreached.

It will be assumed that the card carriage of the record sensing unit has been returned to its normal position, that is, to card column position, at which time latch contacts and floating cam contacts |49 (Fig. 1l) are both closed. It will also Abe assumed that a tape is to be perforated in the 5unitV Baudot code to represent in such code the four numbers represented on the record card C by coded perforations according to the Hollerith statistical code.

2, and! code positions to represent the numeral 1 (see Fig. 5). After this tape perforating Operation, cam contacts C2 close, thereby directing an impulse by the circuit previously outlined to the escape magnet 40 which spaces the record card to card column 2. Of course, the tape is advanced one step after this tape perforatlng operation.

Upon energization of the escape ,magnet 40, an

voperation of the above describedV escapement mechanism of the sensing unit is effected and floating cam contacts |49 are opened until the next column is presented to the sensing brushes.

detail in the Doty patent, certain tape punch At column position of the card carriage a circuit will be closed from the line 300, through said contacts and |49, contact roll 9|, brush |2, sensing the perforation of column coils of the translating relay RI and control relays RIS and R|4 to, line 30|, energizing said relays;

At the same time a circuit is completed Afrom contacts |49 through the tape punch clutch magnet 280 and cam controlled contacts C| to line 30|, energizing the clutch magnet. 'I'his initiates a cyclic 'operation of the tape perforator. In view of the fact that letter or numeral representing perforations in thecontrol tape must be preceded by a respective code signal or designation, such as fletters or "figures," `the tape is not perforated during this cyclic operation of the machine to represent the digit 1 but is first perforated at code positions 2, 4 and 5 to represent Figure Shift (see Fig. 5). whereby the corresponding punch selecting magnets 290 are energized to effect; code designations on the tape is completely described in the Doty Patent No. 2,340,800 and since it is not involved in the present invention, further description is unnecessary. In this perforating operation it should be noted that RIS, relay is energized to open the Rlla contacts, thereby preventing an impulse from being directed to the escape magnet 40 when cam contact C2 close after the card sensing operation. In the present arrangement the circuit for said magnet 40 is from line 300, through latch contacts 35, through relay contacts Rl5a, relay contacts RISa, through cam contacts C2, escapement control magnet 40, through normally closed DI contacts comprising part of the new circuit arrangement, to line 90|. Since an impulse is not directed to said magnet 40, the

card carriage will not be spaced and it will-re,

main in the column sensing position and the aforementioned selected translating and control relays will remain energized. -The cyclic operation of the tape perforating unit is reinitiated when cam contacts C'| close at the end of the The circuit arrangement v first `tape perforating cycle. During the second cycle of the tape perforator punch by translating circuits described in the Dotypatent, said translating and control relays select the tape punch magnetsnl forperforatingtbetapeatthe I, 2,

magnets 290 will again be energized to perforate the tape to represent 2 in theBaudot code. Following this Vtape perforating operation, the'card carriage of the sensing unit is spaced a card column andthe tape likewise. This will present the third column ofthe cardl to the sensing brushes and the 8 digit representing perforation thereon is sensed and through the translating system the corresponding digit is represented on the tape in the Baudot code. It is thought unnecessary to repeat such operations of the machine since they are merely repetitions of the aforedescribed operations.

After the third column of the record card C.

has controlled the tape perforating operation, the card carriage is spaced to card column position 4, at which time there is a concurrent Vanalysis of the 5 digit representation in card column 4 of the record card C and the perforation at the l index point position of the master card M. The tape perforating operation under control of the record card is now suppressed and instead perforations are made in code positions 3 and 4 of the next column of the tape (see Fig. 5) to represent a comma. This comma in the decimal notation system demarcates the thousands orders of a number from the lower ordered digits. With such coded designations in the perforated tape the latter, when utilized to control a tape controlled printing machine, will cause the comma to be inserted between the hundreds and thousands denominational digits. enabling such' number to be properly read.

When the card carriage comes to rest in the 4 card column position of both the master card l and record card C, a circuit'is closed from the line 300 through latch contacts 35, floating cam contacts |49, to contact roll 50, through the contact brush 53 of the master card sensing means analyzing the perforation at the I index point position of the fourth ca rd column, the C relay,

circuit for the E relay is provided by E2 relay contacts, FC contacts, and latch contacts 2l back to line 24|. Therefore, the E relayis retained energized until the FC contacts open when the card carriage spaces from column 4 to column 5. E relay opens the-E| contacts to break the energizing circuit for the C relay and the purpose of this circuit arrangement is to retain the C'relay energized longenough to control a tape perforating operation and deenergize the C relay after it hasbeen employed'once to control a tape perforating operation andthus prevent a repetition of its use in a following tape perforating cycle, during which cycle the tape is perforated to represent the sensed digit representing perforation on the record card C.

D relay will close its stick contacts D3 and thel cuit of the escapement control magnet 40 so that during the cycle in which the extra coded designations punched on the tape, the circuit l to the escapement control magnet cannot be completed and the card carriage will remain at` card column position 4. At such card column position the perforation at the index point position of the record card will remain to be sensed and certain of the translating and control relays will be energized. Through the translating system of the Doty Patent No. 2,340,800, an attempt will be made to select certain of the tape punch magnets 290. However, prior to the operation 'of the translating system the D relay magnet has transferred its D4, D5, D6, D1 and D8 contacts, thereby 'opening the circuits between the tape punch magnets 290 and the impulse selectingcircuits 306--3I0 of the translating system of theY Doty Patent No. 2,340,800. Energization of relay D through its 4, 5, 6, and 8 relay contacts preventsvthe selection of the tape punch magnetsl 290, thereby suppressing the perforation of the tape in accordance with the 5 perforation of column 4 of the record card C. Since it is assumed that the C magnet has kbeen selected for .energization the latter will close the Cl and'.C2 contacts to select the tape punch magnets 290 toperforate the tape at code positions 3 and 4. This is the coded representationfor the comma as appears in Fig. 4. The energizing circuit is from the line 300, through cam contacts C5, through CI .relay contacts now closed, through D6 contacts 4to the 3 tape punch magnet 290, to line 30|. A similar circuit can be traced for selecting by the C2 contacts 4 tape punch magnet 230. This perforates the tape to represent a comma in the Baudot code. During this tape punch cycle the tape feeding mechanism is operative in the regular way to feed the tape to the nextcolumn and the coded perforations are made on the tape to represent the digit 5V derived from the maintained sensing of the 4 card column of the record card`C. This is performed during the following tape punch cycle by circuits now to be described.

Since the card carriage has not moved but remains at column 4 position. the floating cam contacts |49 are closed at the end `of the 'tape punch cycle and when Cl cam contacts close the next tape punch cycle will be initiated by transmitting an impulse to clutch magnet 280. With the D4-8 contacts now restored to normal, tape punch magnets 290 will beV selected during this next tape punch` cycle in accordance with the perforations appearing in the card column 4 of the record card C. During this tape punch cycle, cam contacts C2 will transmit an impulse to the escapement control magnet to space the carriage from card column 4 to card column 5.

It will be recalled that in the previous tape punch cycle the E relay was energized when cam contacts C2 closed and was held energized by i the closure of the FCcontacts and since the E relay coil opened the El contacts the C relay coil is ineffective to control tape punching during the tape punch cycle now under consideration. Relay coil E deenergizes when the floating cam contacts |49 open at the end of this tape punch cycle. In this manner, punching under control of the C relay is now suppressed and the tape is perforated to represent the digit sensed on column 4 of the record card C and therewith the card carriage will be spaced, and successive tape punching cycles will ensue to punch Athe tape to represent the digits of card columns 4, 5 and 6.

Upon completion of punching the tape to represent the digit 8,- the card carriages escape to card column position 'l at which time an extra tape punching operation will be effected in the manner just described, but a different code punching takes place on the tape.

At card column position 1 of the record card sensing unit, two successive tape punching operations are effected, the first of which causes the perforation of the tape at the 3 code positionto represent a space. When this code position is interpreted to' control a tape controlled typewriter, a space will be effected between the'units digit 8, of the printed number 128, 538 and 6, or the hundreds digit of the next printed number 621, asappears over the tape in Fig. 5. The following tape punching operation causes the perforation of the tape to represent the digit 6. The extra tap( punching operation to represent a space is effected by substantially the same circuit connections described for pcrforating the tape to represent the comma designation, except that in this case, since the perforation is at the 3 index point position of card column 1 of the master card M, the A relay will lbe energized. The A relay closes the A| vrelay contacts so that when C5 contacts close the 3 tape punch magnet will be selected for operation. In the following tape punch cycle the statistical card C controls the punching of the tape to represent the "6" digit. Thereafter, punching of the tape to represent the digits 2 and 1 derived from the card columns 8 and 9 of the record card C will be effected on the tape 200. At card column I0, the master card is perforated to initiate an extra tape punching operation tmagain perforate the tape to represent the space designation, this being effected by again energizing the space control relay A.

In tape punching under control of the third card field, it will be noted that at column I2 of the master card, a perforation is sensed at the 8 index point position. This selects the' B relay At card column |4 of the master card, relay A. is energized to again efl'ect the perforation of the 5 tape to represent the space and at column l5 to represent a comma by vcoded designations in the manner previously described. Upon sensing the last card column Isvof this card field the card carriage is skippedto the last card column position and thereafter the record card sensed is ejected from the machine, and a following record Y card is placed upon the card carriage and a repetition of the above described operations then those shown which `are merely selected by way of example. Additional relays F, G, may be supplied beycnd those designated A, B, Aand C and selected by other index point positions. 'I'he particular code positions which are perforated on the tape can be varied merely by the change in wiring between the contacts of the A, B, C and other relays F, G and the punch selecting magnets. Hence, the extra designations placed upon the tape can be varied at will.

While there have been shown and described and pointed out the fundamental novel features of the invention, it will be understood that vari ous omissions and substitutions and changes in the form and detalls of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.- It is the vintention therefore to be limited only as indicated by the scope. of the following claims.
